RESUMEN
ABSTRACT: With a rise in gun violence in the United States, surgeons are tasked with effectively managing penetrating facial trauma. The purpose of this study is to assess methods used for successful composite reconstruction of each anatomical facial subunit following penetrating trauma. A retrospective chart review was performed in subjects undergoing craniofacial reconstruction following penetrating trauma. Reconstructive methods were analyzed through operative reports. Subjects were categorized by anatomical subunit reconstructed (mandible, maxilla (malar complex and roof/palate), orbit, and cranium) and method of reconstruction (open reduction internal fixation only, bone graft, free flap, implant, and tissue expansion). Thirty-six subjects underwent reconstruction for penetrating facial trauma. Involved subunits include 24 mandible, 11 malar complex, 13 palate, 18 orbit, and 11 cranium. Predominate reconstruction method was open reduction internal fixation only for mandible (45.8%), bone grafting for malar complex (81.8%), implant for orbit (66.7%) and cranium (63.6%), and local tissue rearrangement for palate (84.6%). The predominate bone graft donor site was iliac for mandible (42.9%), rib for malar complex (36.3%) and orbit (40.0%), and frontal bone for cranium (42.8%). The predominate free flap was osteocutaneous for all mandible, orbit, and cranium and 7 of 10 (70.0%) palate reconstructions. Tissue expansion was used in all subunits except cranium. In conclusion, bone grafting, implants, free tissue transfer, and tissue expansion are all viable reconstruction options for penetrating trauma. There is no single approach to use, and decisions regarding definitive reconstruction method should be based upon anatomical subunit involved and the size/area of defects.
